The second-largest diamond ever found at Karowe was the 812.77-carat “Constellation” diamond, which was discovered just a few days after the Lesedi La Rona in the fall of 2015. The Constellation sold in May 2016 for $63 million.

Lucara CEO Eira Thomas said that this year the company is focused on mining at the high-value south lobe, which is known as a consistent source of diamonds weighing more than 10.8 carats.

In Q1 2018, Lucara reported that it recovered 218 “specials” (diamonds that are more than 10.8 carats), including four diamonds greater than 100 carats.

The 472-carat diamond will be sold alongside other exceptional stones at a tender set to take place later this year, Thomas said.
